Abstract    The heat pipe applications have been coupled with the renewable energy such as solar energy, waste heat and geothermal energy. Thermosyphon Rankine Cycle (TRC) is a vertical wickless heat pipe engine. In this engine, the turbine is installed between the insulated section and a condenser section of thermosyphon. The mechanical energy developed by the turbine can be converted to electricity, by direct coupling to an electrical generator. Present work simulation results showed that the enhanced TRC model is able to increase the efficiency of the TRC system. This paper introduces the miscellanies new ways in order to improve the performance of a TRC system for supplying the sustainable electricity. For example, the increasing percent of the turbine useful efficiency due to the superheating process was obtained as 0.78% .

چکیده    کاربردهای لوله ی گرمایی با انرژیهای تجدیدپذیر نظیر انرژی خورشیدی، گرمای هدر رونده و انرژی زمین گرمایی گره خورده است. چرخه ی را نکین ترموسیفونی (TRC) یک موتور لوله گرمایی قایم و بدون فتیله است. در این موتور توربین بین قسمتهای بی دررو و چگالنده ی ترموسیفون نصب میشود.. انرژی مکانیکی بدست آمده از توربین که مسقیما با ژنراتور برق درگیر است؛ به الکتریسته تبدیل میشود. نتایج شبیه سازی کار حاضر نشان داد که مدلی بهبود یافته از TRC قادر به افزایش دادن کارآیی سیستم TRC معمولی میباشد. این مقاله به معرفی راه های متنوع جدید به منظور بهبود دادن به کارآیی سیستم معمولی TRC برای تامین الکتریسته ی پایدار می پردازد.. برای مثال درصد افزایشی کارآیی مفید توربین در نتیجه ی فرایند فوق گرم کردن 78/0 درصد حاصل شد.
